KNIFE-BLADE-SWAGING MACHINE.

Specification of Letters Patent.

Patented Mar. 24, 1914.

Application filed August 27, 1912. Serial No. 717,261.

To all whom it may concern Be it known that I, THOMAS E. Moonn, a citizen of the United States, and a resident of Walden, in the county of Orange and State of New York, have invented certain new and useful Improvements in Knife- Blade-Swaging Machines, of which the following is a specification.

The object of the invention is to provide a highly efficient machine for swaging or forming the beveled surfaces on the forward edges of the back of knife blades with accuracy and reasonable rapidity.

I will preferably construct the machine of my invention to treat or swage two knife blades at one time, although, if desired, one blade at a time maybe swaged, first on one side and then on the other with the use of my invention.

The machine of my invention comprises a rotary, abrasive or swaging wheel. suitable means for correctly supporting a blade or blades, and means preferably actuated by a foot treadle for moving the same to carry the blade or blades against said wheel and there holding the same untiLthe proper surfaces have been formed on the exposed side of the blade or blades, after which, uponthe release of the foot from the foot treadle, the blade carrying means will automatically re cede from the abrasive wheel and the blade or blades be reversed in the cla ping means and then again returned to t e abrasive wheel to be swaged on the then exposed side or sides thereof.

I preferably construct the machine of my invention with a blade supporting plate and clamping means for properly holding, two

blades for presentation at the same time to the abrasive wheel so that the beveled surfaces on the outer edges 0 one face of said blades may be simultaneously formed at one operation ofthe machine and that thereafter, upon the blades being reversed in their relation to each other ortransposed in position and turned over, the other face of said blades may, at the succeeding operation of the machine, have the requisitebeveled surby which the swaging of the blades may be performed with extreme accuracy and automatlcally upon the presentation of the blades on the actuation of a foot treadle to the abrasive wheel, which will be driven by power.

The invention will be fully understood from the detailed description hereinafter presented reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation, partly broken away, of a machine constructed in accordance with and embodying the invention, the movable parts of the machine being shown in. their operative relation to the abrasive wheel by solid lines and in their inoperated position by dotted lines; Fig. 2 is a top view of the same; Fig. 3 is-an enlarged detached view of the blade carrying plate, with the clamp for binding the blades against the plate indicated by dotted lines;v Fig. i is adetached side elevation of the clamp for binding the blades against the blade carrying plate; Fig. 5 is an end view of the same taken from the right hand. end of Fig. 1', Fig. 6 is a detached'side elevation of the bed also the clamping means shown in Figs. 4 and 5; Fig. 7 is a face view of the same taken from the right hand side of Fig. 6; Fig. 8 is a detached edge'view of the pivoted frame for supporting the bed member shown in Figs. 6 and 7 Fig. 9 is a face View of the same taken from the right hand side of Fig. 8; Fig. 10 is an edge View of a movable carriage mounted upon the bed plate of the machine and arranged to pivotally support the frame shown in Figs. 8 and 9, and Fig.

the right hand end of Fig. 10.

In the drawings, 15 designates the general supporting frame of the machine which may be mounted upon a bench or upon legs or other support, said frame preferably being an integral casting having sides 16 which support the operative parts of the machine. The sides 16 at the rear portion of the frame 15 extend upwardly to a suitable extent to afford a bearing 17 for the shaft 18 of the swaging or abrasive wheel .19, which preferably will be driven by power through a belt wheel 20, the rear *portions of the sides 16, together with the end portion 21 of the frame 15, creating a box formation within which the wheel 19 y is partly inclosed, as shown.

for carrying the blade supporting plate and 11 is a rear view bf the same, taken from The wheel 19, in the illustration of my invention presented herein, is adapted'to act upon two blades at one time, and in consequence is formed on its periphery with two corresponding annular grooves 22, whose purpose will be more fully understood from the description hereinafter presented. The

wheel 19 may be constructed of any suitable abrasive substance. v

The forward portions of the sides 16 of the main frame 15 have formed upontheir upper edges. Vs or guide rails 23, upon which is mounted the adjustable bed plate 24 for the operative parts of the machine having to do with supporting and applying the blades to the wheel 19 andremoving the blades therefrom. 4 The bed late 24 extends transversely from one si e of the machine to the other and is adjustable on the Vs or guide rails 23 by means of the screw 25. After proper adjustment the bed plate 24 may be secured in fixed position by means of the screw 26 entering the lower side of said bed plate andhaving a head which engages an angle iron piece 27 whose horizontal member is in en agement with the lower edge 28 of a part 0' one side 16 of the main frame, the vertical member of said angle piece 27 being in engagement with the lower opposite edges laterally extending ears 39- carrying ad usting screwsf40, said ears be-- "tion. from said wheel 19,

side of .the bed plate 24 and the head on said screw 26 being adapted to bind against the horizontal member of said angle iron piece. Q

The bed plate 24 is formed at its rear end with 'two vertical standards 29 (Figs. 10 and 11) and at its front end with two bearings '30 for ashaft 31, u on which an operating crank 32 connecte with a pitman rod 33 and foot treadle 34, is secured, the purpose of saidcrank, pitinan rod and foot treadle being to impart at the proper time a partial rotary or rocking movement to the shaft 31 for effecting therewiththe 0 eration of certain other parts of the mac ine presently to be described. The standards 29 are integral with the bed plate 24,1and said standards on pivot screws 35 pivotally support the frame 36 (Figs. 8 and 9), which is adapted to have a swinging motion on the. screws .35 toward and from the abrasive wheel 19, the movement of said frame 36 toward the wheel 19 being eflected .by the operator pressing on the treadle 34 and the reverse movement of said frame, or to its normal Loesit'i'on in a direcing effected by a sprin .37 coiled upon a rod portion 38 of said frame andrat. its lower portion flexed against the bed plate 24. The spring 37 acts to yieldingly hold the frame 36 in its receded or normal position illustrated by dotted lines in 1. The frame 36 has at its ing the end portions of a transverse bar 41 cast integrally with the frame 36 and projected at its ends in the plane of the standards 29 between which the body of the frame 36 is held and has its movement. The

ends of the bar 41 forming the cars 39 preward the abrasive wheel 19 under the action of the foot treadle 34 may thus be adjusted by will by means of the stop screws 40,

which on each forward thrust of the frame 36 engage the standards 29 and arrest said frame. The throw of the frame 36 in opposition to the force of the spring 37 and in a direction toward the abrasive wheel 19 or from the dotted position of said frame shown in Fig. 1 to the position illustrated solid lines, is accomplished through a cra arm 42 secured on the operating shaft 31 and pivotally connected with the link '43, whose o erative connections will be hereinafter re erred to.

The upper portion of the frame 36 pivotally supports upon the pivot screws .44 the bed 45 which carries the blade supporting plate 46, said bed 45 being disposed at the rear side of theupper portionof the frame 36 or between said frame and the abrasive wheel 19, as more clearly illustrated in Fig. 1, and having a forwardly projectin lug 47 formed with bearin recesses 48 Eor said pivot screws 44, as s own in Figs. 6 and 7 The bed 45 is also formed with upwardly and frontwardly extending ears 49 through which a pin 50 passes upon which and between sald cars is mounted a bar 51 carrying intended for use in supporting two blades,

as shown in Fig. 3, is equipped with two gages 54 adapted to engage the kicks ofthe blades and adjustable-by means of screws 55 so as to adapt them for blades differing in character. I number the two blades shown in ,Fig. 3 as 56, 57, and as illustrated said blades lie against the plate 46 and are supported at their lower edges by dowel pins 58 and incline downwardl toward each other. For purposes of description I number the swaged or beveled surfaces of the blades The clamp 52 is secured upon the end of the bar 51 by means of a screw 60,and said clamp may be adjusted ertically on the bar 51 by reason of the fact that the screw 60 passes throligh the vertical slot 61 in said clamp. The adjustment of the-clamp 52 is desirable in adapting the same to blades differing in character. The clamp 52 is a fan-shaped plate, and in the present I instance is formed at its lower edges with two corresponding beveled and curved surfaces 62 corresponding with the curvature of the annular grooves 22 in the wheel 19, it being the intention that, in use, the wheel 19 may rotate in close relation to the lower portions of the clamp 52 without grinding against the same. The clamp 52 is secured in 'afixed re lation to the bar 51, but since the bar 51 is pivotally mounted between the cars 49 of the bed 45, said clamp is adapted to have a rocking motion toward. andfrom said bed and consequently toward and from the plate 46 and blades 56, 57 supported thereby. I indicate by dotted lines in Fig. 3 the position of the clamp 52 with relation to the blades 56, 57 when said clamp is in its operative position binding said blades against the plate 46.

From the foregoing description it will be,

seen that the frame 36 is pivotally mounted at its lower end over the main bed plate or blade supporting plate 46 is pivotally mounted in the upper end of said frame 36, and that the clamp bar 51 is ,pivotally mounted between the ears 49 at the upper end of said bed 45. When these parts just referred to are released to take their normal position or the relation to one another illustrated by dotted lines in Fig. 1, the spring 37 acts to swing the upper portion of the frame 36 frontwardly and the treadle-spring 64 acting through the shaft 31, crank-arm .42 and link 43 exerts a'forward and downward pulling action on the clamp-bar 51, whereby the bed 45 takes almost a horizontal position, the clamp arm 51 hearly a vertical position, and the clamp 52 an elevated position above the blade plate 46 and blades that may be at the time thereon. When the blades have been applied upon the plate 46, with the latter. on the bed 45, and it is desired to move the blades against the abrasive.

wheel '19, the operator" will press downwardly on the foot treadle 34 and thereby through the crank arm 32 turn the shaft 31 downwardly toward the front and cause it to move the rear end of the crank arm 42 upwardly, thereby through the link 43 rocking theclamp' bar 51'rearwardly and downwardly andcausing the clamp 52 to bind against th'e'knife-blades on the plate 46, folcarriage' 24, that the bed 45 carrying the lowing which action the continued upward movement of the crank arm 42 and link 43 effects the rocking rearwardly of the bed 45 without disturbing its relation to the clamp 52 and finally in the movement of the frame 36 to its; vertical position or until the stop screws 40 thereon become arrested by the standards 29 of the main bed or carriage 24, under which condition the knife blades will have become carried against the wheel 19 and the latter will form thereon the swaged or beveled surfaces 59.

I provide in the upper portion of the frame 36 a set screw 63, whose inner end is in rear of the bed 45 and which is employed to secure the proper adjustment of the said bed to the grinding wheel so as to adapt the machine to make just the beveled surface 59 desired and also to enable blades differing in character to be swaged by the machine.

When two blades 56, 57 are placed on the .plate 46 and presented to the wheel 19, both blades will be acted on simultaneously, and

in order that two blades may thus betreated ,at one time I form the wheel 19 with the and transposed in position and turned over on the plate 46, so that the pile-side of the blade 56 may become exposed at the v right hand side of the plate 46' and the name-side of the blade 57 become exposed at the left hand side of said plate 46, and thereupon at the succeeding operation of the machine the said blades will have the swaging completed, the first operation hav-' ing completed the name-side of the blade 56 and pile-side of the blade 57, and the second operation having finished the pileside of the blade 56 and the name-sideof the blade 57.

ence of the two annular grooves 22in the wheel 19, but obviously the work of swaging knife blades may be very greatly expedited by treating two blades at the same time, as

against treating one blade at a time. Nor do I limit my invention to all of the details of form, construction and arrangement illustrated, since obviously the machine is susceptible of modification in respect to its details' What I claim as my invention and desire to secure by Letters'Patent, is:
